Packers Hall of Famer Johnnie Gray was the guest on Monday's season premiere of Clubhouse Live, USA TODAY NETWORK-Wisconsin’s live weekly football show.

Among the topics he touched on were the NFL's tackling rules, preseason football and Packers defensive coordinator Mike Pettine. The show can be seen live at The Clubhouse Sports Pub & Grill in downtown Appleton or at clubhouselive.com.

Q: You're a former hard-hitting safety. What's your take on the NFL's new tackling rule this season? Is it an overreaction. Or, is it a case in which players today simply need to learn how to tackle correctly?

Gray: I don't think it's an overreaction. You want to get rid of the spearing. Spearing has been outlawed ever since way back when, but guys still go out there and lead with their heads. And they try to throw their bodies like a projectile, and that's what they want to get rid of. Not only is it hurting the player being hit, but it also affects you with spinal damage and things like that. But you're finding players - guys throwing their bodies out the first series of the game, and all of sudden this guy's out for the rest of the season.

Q: You played in an era when training camp consisted of two-a-day practices and preseason schedules were six games. But do you think players today even need four preseason games given teams' offseason workout schedules and OTAs? Should training camp practices be cut even further?

Gray: I don't know if it's too much. Maybe you could go to three (preseason) games. You should be able to get some evaluation. I think they should maybe do it something like baseball where I think maybe you play three preseason games, you get through maybe two regular season games, and then you cut down to maybe 65 (players) or 68. And then you make another cutdown and get to the practice squad. And then there should not be this ... if you have a 53-man roster, it shouldn't be 48 guys out there playing. It should be 53 out there, and then you still have the practice squad.

I just think you still need to be evaluating. Guys like (rookie wide receiver) J'Mon Moore - if you only play two preseason games, your top wide receiver (draft) pick would not be on the squad. Now after the third preseason game, you're thinking, 'OK, I've seen him practice for the last three weeks, and now I've had the chance to see it in a game.' Now I need one more week and you see him shine again, you're going to be thinking, 'OK, that's the reason why we're playing four preseason games.'

Q: The defense hasn't shown a whole lot in the preseason, but what are your initial impressions of new defensive coordinator Mike Pettine? What noticeable changes should fans expect to see defensively under his watch?

Gray: I think communication. Keeping it simple for these guys to go out there and just line up and play. To be able to see the (rookie) corners, you drafted them for a reason - because you see them making plays. It would be different if they were out there kind of running around and everybody's looking at each other. No one's sitting there hitting themselves on the chest saying, 'Hey, that's my bad. I should have been there.' Or looking at guys (with) hands up in the air like we saw last year in Week 17 for God's sakes, still blowing coverages. So I think it's fundamentals, technique and communication is what Coach Pettine brings to the table.
